We look at the division of 21993721 by 326 
We're looking to find how many times 326 goes into 21993721.

Advancing to step 1:
326 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 326

Let's proceed to step 2:
The number 326 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (9) from the dividend to 21 and continue with: 219 / 326

Advancing to step 3:
326 goes into 219 0 times with a remainder of 219.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 219, we get 219.
Append the next digit (9) from the dividend to 219 and continue with: 2199 / 326

On to step 4:
326 goes into 2199 6 times with a remainder of 243.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 1956 away from 2199, we end up with 243.
Append the next digit (3) from the dividend to 243 and continue with: 2433 / 326

Going ahead to step 5:
When dividing 2433 by 326, we get 7 with a remainder of 151.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
The remainder is 151 after subtracting 2282 from 2433.
Bring next digit (7) of the dividend behind the 151 and repeat the process: 1517 / 326

Let's proceed to step 6:
326 goes into 1517 4 times with a remainder of 213.
Write down 4 as next digit of the result. 
Result so far: 674.0
If we subtract 1304 from 1517, we get 213.
Include the next digit (2) from the dividend after 213, then repeat: 2132 / 326

Step 7:
If we divide 2132 by 326, we get 6 and a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 6746.0
Subtracting 1956 from 2132 leaves us with 176.
Bring next digit (1) of the dividend behind the 176 and repeat the process: 1761 / 326

Let's proceed to step 8:
When dividing 1761 by 326, we get 5 with a remainder of 131.
The number 5 becomes the next digit in our result. 
Result so far: 67465.0
If we take 1630 away from 1761, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Going ahead to step 9:
If we divide 1310 by 326, we get 4 and a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 67465.4
If we take 1304 away from 1310, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
The number 326 fits into 60 0 times, leaving a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 67465.4
The remainder is 60 after subtracting 0 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
The number 326 fits into 600 1 times, leaving a remainder of 274.
Write down 1 as next digit of the result. 
Result so far: 67465.401
Subtract 326 from 600 to get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Going ahead to step 12:
326 goes into 2740 8 times with a remainder of 132.
Record the quotient 8 as the next digit in the result. 
Result so far: 67465.4018
Deduct 2608 from 2740 and we're left with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

On to step 13:
1320 divided by 326 is 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 67465.40184
Subtracting 1304 from 1320 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 14:
If we divide 160 by 326, we get 0 and a remainder of 160.
The next digit of our result is 0. 
Result so far: 67465.40184
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 15:
The number 326 fits into 1600 4 times, leaving a remainder of 296.
The number 4 becomes the next digit in our result. 
Result so far: 67465.4018404
Subtracting 1304 from 1600 leaves us with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

On to step 16:
326 goes into 2960 9 times with a remainder of 26.
Put 9 as the next digit of the answer. 
Result so far: 67465.40184049
Deduct 2934 from 2960 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 67465.40184049, and the remainder is 2.6e-08.
